This does what Val() used to do, by defaulting a leading zero, you have not changed any of the data within the variable, but have only solved blanks. I did it with a concatenator, in my case (I'm using vb.net ) it was CDbl("0" + txtAmount.Text) where P is the original data your testing for, and then R and N, etc. The value of unsigned integers, long, float, double, and decimal. In my case, since i wasn't able to declare variables, i found an elegant solution this problem. Public Shared Function StrConv( ByVal str As String, ByVal Conversion As, Optional ByVal LocaleID As Integer, ). // compile time error: Cannot implicitly convert type long to int. IF, however, you are expecting numbers in the data, and receiving an error isn't possible (long story short, that is my context) then you HAVE to use CDbl, since there isn't another conversion method that can be used in a single expression (again, my context). Dim MyTime MyTime TimeValue('4:35:17 PM') Return a time. You can also use date literals to directly assign a time to a Variant or Date variable, for example, MyTime 4:35:17 PM. In some cases (mine specifically) TryParse isn't an option (see below for 'why' along with true solution) This example uses the TimeValue function to convert a string to a time. The CDbl function you were attempting doesn't handle blanks very well (it blows up). You can use before adding the Isnumeric to test that. And the InvariantCulture uses the point as separator. a Double.Parse (list (0), CultureInfo.InvariantCulture) Here we pass the information about what locale setting Parse should use in converting the input string to a double. I know this original question is old, but it's trending on Google.Įveryone has been right, to a degree, so far. 1 Sign in to vote Rasol, Probably your textbox contains a blank, a non numeric character or a special characters not comma or decimal point. So in the most basic form you need to change that method to the native.
